• Moving to .net 4 results in System.Transactions Critical: 0

  - by john

  Hi I have fully working project in .net 3.5SP1, with EF 1 ORM. I tried to upgrade to .net 4. No issue while upgrading... Then i ran the project and got a NullExecptionError, with no stack trace... and no way to debug. Looking at the output windows i can read this: System.Transactions Critical: 0 : <TraceRecord xmlns="http://schemas.microsoft.com/2004/10/E2ETraceEvent/TraceRecord" Severity="Critical"><TraceIdentifier>http://msdn.microsoft.com/TraceCodes/System/ActivityTracing/2004/07/Reliability/Exception/Unhandled</TraceIdentifier><Description>Unhandled exception</Description><AppDomain>OTCSouscriptions.vshost.exe</AppDomain><Exception><ExceptionType>System.NullReferenceException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType><Message>Object reference not set to an instance of an object.</Message><StackTrace> at System.Windows.StyleHelper.GetInstanceValue(UncommonField`1 dataField, DependencyObject container, FrameworkElement feChild, FrameworkContentElement fceChild, Int32 childIndex, DependencyProperty dp, Int32 i, EffectiveValueEntry&amp;amp; entry) at System.Windows.FrameworkTemplate.ReceivePropertySet(Object targetObject, XamlMember member, Object value, DependencyObject templatedParent) at System.Windows.FrameworkTemplate.&amp;lt;&amp;gt;c__DisplayClass6.&amp;lt;LoadOptimizedTemplateContent&amp;gt;b__4(Object sender, XamlSetValueEventArgs setArgs) at System.Xaml.XamlObjectWriter.OnSetValue(Object eventSender, XamlMember member, Object value) at System.Xaml.XamlObjectWriter.Logic_ApplyPropertyValue(ObjectWriterContext ctx, XamlMember prop, Object value, Boolean onParent) at System.Xaml.XamlObjectWriter.Logic_DoAssignmentToParentProperty(ObjectWriterContext ctx) at System.Xaml.XamlObjectWriter.Logic_AssignProvidedValue(ObjectWriterContext ctx) at System.Xaml.XamlObjectWriter.WriteEndObject() at System.Xaml.XamlWriter.WriteNode(XamlReader reader) at System.Windows.FrameworkTemplate.LoadTemplateXaml(XamlReader templateReader, XamlObjectWriter currentWriter) Any help appreciated...

• Javascript: Error 'Object Required.'

  - by javascripthelp

  The following is the error popup message I get when I click "Finalize" button on my website: "Line: 298 Char: 5 Error: Object required: 'lobi_c_selected(...)' Code: 0 URL: http://10.128.23.50/i-prostage/AP/w_ap_check_reconciliation.asp?" Normally, when I click "Finalize" button, it'll generate and show a report in a popup window.

• Linked Measure Groups and Local Dimensions

  - by ekoner

  Mulling over something I've been reading up on. According to Chris Webb, A linked measure group can only be used with dimensions from the same database as the source measure group. So I took this to mean as long as two cubes share a database, a linked measure group can be used with a dimension. So I created a new cube and added a local measure group, a local dimension and a linked measure group. However, I can't create a relationship between the linked measure group and the local dimension even though they are within the same database. I get the message below: Regular relationships in the current database between non-linked (local) dimensions and linked measure groups cannot be edited. These relationship can only be created through the wizard. This dialog can be used to delete these relationships. I see that I can go to the original cube and add the dimension there, but does the message below mean I have an alternative? I just know it's going to be something simple and trivial! Thanks for reading.

• wxpython GUI and multiprocessing - how to send data back from the long running process

  - by wxpydon

  Hello everyone, Trying to run a time consuming task from a wxpython GUI. The basic idea is to start the long time task from the GUI (pressing a button) and then, a static text on the dialog should be updated from it. First I tried some threading (http://wiki.wxpython.org/LongRunningTasks and many other resourses seen), and I want to show back the messages using Publisher.class. It didn't went so well, after a message or two, the GUI seems to frozen. Now I want to achieve that with multiprocessing. I have this method inside my 'GUI' class: def do_update(self, e): self.txt_updatemsg.SetLabel("Don't stop this \n") ... pub = Publisher() # i tried also calling directly from dbob object # Publisher() is a singleton so this must be useless? pub.subscribe(self.__update_txt_message, ('updatedlg', 'message')) dbob = dbutils.DBUtils() # DBUtils is the class with 'long time' tasks dbob.publisher = pub p = Process(target=self.do_update_process, args=(dbob,)) p.start() while p.is_alive: wx.Yield def do_update_process(self, dbob): dbob.do_update() __update_txt_message is a simple function what sets the static text on dialog. Question is: how can I send back some text messages from this Process (just simple text, that's all I need) Thanks guys!

• Switch statement usage - C

  - by Jamie Keeling

  Hello, I have a thread function on Process B that contains a switch to perform certain operations based on the results of an event sent from Process A, these are stored as two elements in an array. I set the first element to the event which signals when Process A has data to send and I have the second element set to the event which indicates when Process A has closed. I have began to implement the functionality for the switch statement but I'm not getting the results as I expect. Consider the following: // //Thread function DWORD WINAPI ThreadFunc(LPVOID passedHandle) { for(i = 0; i < 2; i++) { ghEvents[i] = OpenEvent(EVENT_ALL_ACCESS, FALSE, TEXT("Global\\ProducerEvents")); if(ghEvents[i] == NULL) { getlasterror = GetLastError(); } } dwProducerEventResult = WaitForMultipleObjects( 2, ghEvents, FALSE, INFINITE); switch (dwProducerEventResult) { case WAIT_OBJECT_0 + 0: { //Producer sent data //unpackedHandle = *((HWND*)passedHandle); MessageBox(NULL,L"Test",L"Test",MB_OK); break; } case WAIT_OBJECT_0 + 1: { //Producer closed ExitProcess(1); break; } default: return; } } As you can see if the event in the first array is signalled Process B should display a simple message box, if the second array is signalled the application should close. When I actually close Process A, Process B displays the message box instead. If I leave the first case blank (Do nothing) both applications close as they should. Furthermore Process B sends data an error is thrown (When I comment out the unpacking): Have I implemented my switch statement incorrectly? I though I handled the unpacking of the HWND correctly too, any suggestions? Thanks for your time.

• Error getting twitter request token using OAuth and PEAR Services_Twitter

  - by Onema

  Hello, I am moving from the basic authentication method using username and password to the OAuth based authentication. I was using an old version of the pear package Services_Twitter, that did not support OAuth. The latest version of this package supports OAuth authentications, it has a few dependencies (HTTP_Request2, HTTP_OAuth). It was very simple to install them and upgrade the package. I did all this my local machine and had no trouble getting the authentication up and running. I committed this code to the test site, but every time the code request a "request token" I get the following error message "Unable to connect to ssl://api.twitter.com:443. Error #0" I have spend 6 hours making sure that all the pear packages where up to date, checking the customer token and token secret, making sure port 443 is not closed... in addition to various other test. I have exhausted my resources and I come to you in hope to find some answers. Thank you PD: One of the things I do not understand is why does the message says that the url is ssl://api.twitter.com:443 rather than https://api.twitter.com/request_token? the former one is the one I am using to get the request token.

• cannot override a concrete member without a third member that's overridden by both

  - by huynhjl

  What does the following error message mean? cannot override a concrete member without a third member that's overridden by both (this rule is designed to prevent ``accidental overrides''); I was trying to do stackable trait modifications. It's a little bit after the fact since I already have a hierarchy in place and I'm trying to modify the behavior without having to rewrite a lot of code. I have a base class called AbstractProcessor that defines an abstract method sort of like this: class AbstractProcessor { def onPush(i:Info): Unit } I have a couple existing traits, to implement different onPush behaviors. trait Pass1 { def onPush(i:Info): Unit = { ... } } trait Pass2 { def onPush(i:Info): Unit = { ... } } So that allows me to use new AbstractProcessor with Pass1 or new AbstractProcessor with Pass2. Now I would like to do some processing before and after the onPush call in Pass1 and Pass2 while minimizing code changes to AbstractProcessor and Pass1 and Pass2. I thought of creating a trait that does something like this: trait Custom extends AbstractProcessor { abstract override def onPush(i:Info): Unit = { // do stuff before super.onPush(i) // do stuff after } And using it with new AbstractProcessor with Pass1 with Custom and I got that error message.

• User authentication -- username mismatch in IIS in ASP.NET application

  - by Cory Larson

  Last week, an employee's Active Directory username was changed (or a new one was created for them). For the purposes of this example, let's assume these usernames: Old: Domain\11111 New: Domain\22222 When this user now logs in using their new username, and attempts to browse to any one of a number of ASP.NET applications using only Windows Authentication (no Anonymous enabled), the system authenticates but our next layer of database-driven permissions prevents them from being authorized. We tracked it down to a mismatch of usernames between their logon account and who IIS thinks they are. Below are the outputs of several ASP.NET variables from apps running in a Windows 2008 IIS7.5 environment: Request.ServerVariables["AUTH_TYPE"]: Negotiate Request.ServerVariables["AUTH_USER"]: Domain\11111 Request.ServerVariables["LOGON_USER"]: Domain\22222 Request.ServerVariables["REMOTE_USER"]: Domain\11111 HttpContext.Current.User.Identity.Name: Domain\11111 System.Threading.Thread.CurrentPrincipal.Identity.Name: Domain\11111 From the above, I can see that only the LOGON_USER server variable has the correct value, which is the account the user used to log on to their machine. However, we use the "AUTH_USER" variable for looking up the database permissions. In a separate testing environment (completely different server: Windows 2003, IIS6), all of the above variables show "Domain\22222". So this seems to be a server-specific issue, like the credentials are somehow getting cached either on their machine or on the server (the former seems more plausible). So the question is: how do I confirm whether it's the user's machine or the server that is botching the request? How should I go about fixing this? I looked at the following two resources and will be giving the first one a try shortly: http://www.interworks.com/blogs/jvalente/2010/02/02/removing-saved-credentials-passwords-windows-xp-windows-vista-or-windows-7 http://stackoverflow.com/questions/2325005/classic-asp-request-servervariableslogon-user-returning-wrong-username/5299080#5299080 Thanks.

• Reverse ordered list for jquery submitted comments

  - by g-man

  Hey guys I have one more question lol. I am using a script that allows users to submit comments through jquery ajax, however when they are submitted, the submitted comments submit at the bottom of the other comments which are sorted in descending order (newest on top) when the page first loads (due to mysql query). Is there a way to make it submit on top through some sort of sorting javascript function? function prepare(response) { var d = new Date(); count++; d.setTime(response.time*1000); var mytime = d.getHours()+':'+d.getMinutes()+':'+d.getSeconds(); var string = '<li class="shoutbox-list" id="list-'+count+'">' + '<span class="date">'+mytime+'</span>' + '<span class="shoutbox-list-nick"><a href="statistics.php?user='+response.user+'">'+response.user+'</a>:</span>' + '<span class="msg">'+response.message+'</span>' +'</li>'; return string; } function success(response, status) { if(status == 'success') { lastTime = response.time; $('#daddy-shoutbox-list').append(prepare(response)); $('input[name=message]').attr('value', '').focus(); $('#list-'+count).fadeIn('slow'); timeoutID = setTimeout(refresh, 3000); } } <div id="daddy-shoutbox"> <ol id="daddy-shoutbox-list"></ol> </div>

• C++ boost.asio server and client connection undersanding

  i started learning boost.asio and i have some problems with undersanding tcp connections. There is example from official boost site: #include <ctime> #include <iostream> #include <string> #include <boost/asio.hpp> using boost::asio::ip::tcp; std::string make_daytime_string() { using namespace std; // For time_t, time and ctime; time_t now = time(0); return ctime(&now); } int main() { try { boost::asio::io_service io_service; tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), 13)); for (;;) { tcp::socket socket(io_service); acceptor.accept(socket); std::string message = make_daytime_string(); boost::system::error_code ignored_error; boost::asio::write(socket, boost::asio::buffer(message), boost::asio::transfer_all(), ignored_error); } } catch (std::exception& e) { std::cerr << e.what() << std::endl; } return 0; } there is question, why if i want to connet to this server via client i have t write: boost::asio::io_service io_service; tcp::resolver resolver(io_service); tcp::resolver::query query(host_ip, "daytime"); //why daytime? tcp::resolver::iterator endpoint_iterator = resolver.resolve(query); tcp::resolver::iterator end; why daytime?, what it meant and where it is inicialized in server, or i just doesn't missed somefing? there is full client code : www.boost.org/doc/libs/1_39_0/doc/html/boost_asio/tutorial/tutdaytime1.html thanks for explanation in advance

• Playing wave file ends immediatly (C++, Windows)

  - by TyBoer

  I've got a following situation. On a machine there is a Fritz ISDN card. There is a process that is responsible for playing a certain wave file on this device's wave out (ISDN connection is made at startup and made persistent). The scenario is easy, whenever needed the process calls waveOutWrite() on the previously opened wave device (everything initialized without any problems of course) and a callback function waits for MMWOMDONE msg to know that the playback has been finished. Since a few days however (nothing changed neither in the process nor the machine) the MMWOMDONE message comes immediately after calling waveOutWrite() even though the wave lasts a couple of seconds. Again no error is reported, it looks like the file was played but had zero length (which is not the case). I am also sure that waveOutReset() was not called by my process (it would also trigger sending the mentioned message). I already used to have some strange problems in the past that where solved simply by reinstalling TAPI drivers. This time for some reason it is problematic form me to perform that once again and am trying more analytical approach :). Any suggestions what might cause such a behavior? Maybe sth on the other end of the ISDN line?

• What is the fastest collection in c# to implement a prioritizing queue?

  - by Nathan Smith

  I need to implement a queue for messages on a game server so it needs to as fast as possible. The queue will have a maxiumem size. I need to prioritize messages once the queue is full by working backwards and removing a lower priority message (if one exists) before adding the new message. The appliation is asynchronous so access to the queue needs to be locked. I'm currently implementing it using a LinkedList as the underlying storage but have concerns that searching and removing nodes will keep it locked for too long. Heres the basic code I have at the moment: public class ActionQueue { private LinkedList<ClientAction> _actions = new LinkedList<ClientAction>(); private int _maxSize; /// <summary> /// Initializes a new instance of the ActionQueue class. /// </summary> public ActionQueue(int maxSize) { _maxSize = maxSize; } public int Count { get { return _actions.Count; } } public void Enqueue(ClientAction action) { lock (_actions) { if (Count < _maxSize) _actions.AddLast(action); else { LinkedListNode<ClientAction> node = _actions.Last; while (node != null) { if (node.Value.Priority < action.Priority) { _actions.Remove(node); _actions.AddLast(action); break; } } } } } public ClientAction Dequeue() { ClientAction action = null; lock (_actions) { action = _actions.First.Value; _actions.RemoveFirst(); } return action; } }

• Can't return a List from a Compiled Query.

  - by Andrew

  I was speeding up my app by using compiled queries for queries which were getting hit over and over. I tried to implement it like this: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id) End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, List(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ (From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u).ToList()) This did not work and I got this error message: Type : System.ArgumentNullException, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : Value cannot be null. Parameter name: value However, when I changed my compiled query to return IQueryable instead of List like so: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id).ToList() End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, IQueryable(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u) It worked fine. Can anyone shed any light as to why this is? BTW, compiled queries rock! They sped up my app by a factor of 2.

• CrystalDecisions.Web reference version changes suddenly when run the webapp

  - by Somebody

  I'm breaking my head with this issue, I have a webapp that has a report using crystal report, in the development pc it works fine, but when copy the same project to another pc, when I load the project (VS 2003) the following msg appears: One or more projects in solution need to be updated to use Crystal Reports XI Release 2. If you choose "Yes", the update will be applied permanently... I choose "Yes" and after that I can see that CrystalDecisions.Web reference has the correct version, and location according to the develpment machine, in this case: 11.5.3300.0. But when run the webapp, I can see when the version and path suddenly changes to: 11.0.3300.0. And when trying to see the report the following error appears: Parser Error Message: The base class includes the field 'CrystalReportViewer1', but its type (CrystalDecisions.Web.CrystalReportViewer) is not compatible with the type of control (CrystalDecisions.Web.CrystalReportViewer). the asp.net has the following: <%@ Register TagPrefix="cr" Namespace="CrystalDecisions.Web" Assembly="CrystalDecisions.Web, Version=11.5.3300.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" %> How is this possible? what's happening here? EDIT This is what I did: the wrong version (11.0.3300.0) was located at: C:\Program Files\Common Files\Business Objects\3.0\managed and the right version (11.5.3300.0) is located at: C:\Program Files\Business Objects\Common\3.5\managed So I just deleted the files of the wrong solution, and I made it work in my new computer, no more errors when running the webapp, the report shows fine. But when try to do the same thing in production server, a different error came out, now an exception: This report could not be loaded due to the following issue: The type initializer for 'CrystalDecisions.CristalReports.Engine.ReportDocument' threw an exception.

Below is the code for the controller library: public static function includeFileContainingClass($classname) { $classname_rectified = str_replace(__NAMESPACE__.'\\', '', $classname); $controller_path = ENVIRONMENT_DIRECTROY_CONTROLLERS.strtolower($classname_rectified).'.controller.php'; if (file_exists($controller_path)) { include $controller_path; return true; } else { // TODO: Implement gettext('MSG_FILE_CONTROLLER_NOTFOUND') throw new Exception('File '.strtolower($classname_rectified).'.controller.php not found.'); return false; } } And here's the code of the file I try to invoke the autoloader on: try { spl_autoload_register(__NAMESPACE__.'\\Controller::includeFileContainingClass'); } catch (Exception $malfunction) { die($malfunction->getMessage()); } // TESTING ONLY $test = new Testing(); When I try to force a malfunction, I get the following message: Fatal error: Uncaught exception 'Exception' with message 'File testing.controller.php not found.' in D:\cerophine-0.0.1-alpha1\application\libraries\controller.library.php:51 Stack trace: #0 [internal function]: application\Controller::includeFileContainingClass('application\Tes...') #1 D:\cerophine-0.0.1-alpha1\index.php(58): spl_autoload_call('application\Tes...') #2 {main} thrown in D:\cerophine-0.0.1-alpha1\application\libraries\controller.library.php on line 51 What seems to be wrong?

• Close application on error

  - by poke

  I’m currently writing an application for the Android platform that requires a mounted SD card (or ExternalStorage). I know that it might not be the best way to require something like that, but the application will work with quite a lot of data, and I don’t even want to think about storing that on the device’s storage. Anyway, to ensure that the application won’t run without the external storage, I do a quick check in the activity’s onCreate method. If the card is not mounted, I want to display an error message and then quit the application. My current approach looks like this: public void onCreate ( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( R.layout.main ); try { // initialize data storage // will raise an exception if it fails, or the SD card is not mounted // ... } catch ( Exception e ) { AlertDialog.Builder builder = new AlertDialog.Builder( this ); builder .setMessage( "There was an error: " + e.getMessage() ) .setCancelable( false ) .setNeutralButton( "Ok.", new DialogInterface.OnClickListener() { public void onClick ( DialogInterface dialog, int which ) { MyApplication.this.finish(); } } ); AlertDialog error = builder.create(); error.show(); return; } // continue ... } When I run the application, and the exception gets raised (I raise it manually to check if everything works), the error message is displayed correctly. However when I press the button, the application closes and I get an Android error, that the application was closed unexpectedly (and I should force exit). I read some topics before on closing an application, and I know that it maybe shouldn’t happen like that. But how should I instead prevent the application from continuing to run? How do you close the application correctly when an error occurs?

• Using authsmtp from a Grails server

  - by Simon

  This is quite a specific question, and I have had no luck on the grails nabble forum, so I thought I would post here. I am using the grails mail plug-in, but I think my question is a general one about using authsmtp as an email gateway from my server. I am having trouble sending mail from my app using authsmtp. I have installed and configured the mail plugin and was originally using my ISP's SMTP server to send mails. However when I deployed to AWS EC2 this failed because my elastic IP was blocked by the SMTP host. So I bought myself an authsmtp account and set up my server email address as an accepted one at authsmtp. I then changed my configuration in SecurityConfig.groovy to point to the authsmtp server that I had been designated... mailHost = "mail.authsmtp.com" mailUsername = "myusername" mailPassword = "mypassword" mailProtocol = "smtp" mailFrom = "[email protected]" mailPort = 2525 ...and I'm just trying to get this to work locally before I deploy back up to AWS. Sending mail fails and in my log I have this exception: 2010-02-13 10:59:44,218 [http-8080-1] ERROR service.EmailerService - Failed to send emails: Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 513 5.0.0 Your email system must authenticate before sending mail. org.springframework.mail.MailSendException; nested exception details (1) are: Failed message 1: com.sun.mail.smtp.SMTPSendFailedException: 513 5.0.0 Your email system must authenticate before sending mail. at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388) at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:959) at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:583) I'm a bit lost since the username and password I provide in the configuration are definitely correct. A terse and not very helpful conversation with authsmtp support suggests that I need to MD5 and/or base64 encode my credentials before sending, so my question is in three parts... 1) any idea what's going on with the failure and why that message is appearing? 2) how would I encode the credentials to pass to authsmtp and how would I configure that for the mail plugin 3) has anyone successfully connected and sent mail through authsmtp from the mail plugin and specifically from AWS EC2?

• dialing on iphone/ipod touch not working with documented procedures

  - by dave

  I'm trying to set up an iphone app to the phone number of a various sports store using the tel:// url passing method- I am developing on an ipod touch- usually on the touch you see the error message "Unsupported URL - This URL wasn't loaded tel://99887766" when you try and dial a number. I cant get this message to appear on the simulator or the ipod touch. do I need to do some sort of fancy signing before the app will dial properly? I am using this code: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", [selectedBar phoneNumber]]]]; and I've tried adding the slashes: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel://%@", [selectedBar phoneNumber]]]]; but neither work. I have also tried this way: [[UIApplication application] openURL:[NSURL URLWithString:@"tel://99887766"]]; and this way: NSMutableString *phone = [[@"+ 12 34 567 89 01" mutableCopy] autorelease]; [phone replaceOccurrencesOfString:@" " withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [phone length])]; [phone replaceOccurrencesOfString:@"(" withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [phone length])]; [phone replaceOccurrencesOfString:@")" withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [phone length])]; NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", phone]]; [[UIApplication sharedApplication] openURL:url]; No matter what i do i can't get any response from the simulator / ipod touch that it is dealing with a phone number- When I press the button associated with this code, it doesnt crash, it's like its processed it and decided not to do anything. i even put an NSLog(@"button called"); in just before the code to confirm the button was working, which it is.

• ssh_exchange_identification: Connection closed by remote host under Git bash

  - by MoreFreeze

  I work at win7 and set up git server with sshd. I git --bare init myapp.git, and clone ssh://git@localhost/home/git/myapp.git in Cywgin correctly. But I need config git of Cygwin again, I want to git clone in Git Bash. I run "git clone ssh://git@localhost/home/git/myapp.git" and get following message ssh_exchange_identification: Connection closed by remote host then I run "ssh -vvv git@localhost" in Git Bash and get message debug2: ssh_connect: needpriv 0 debug1: Connecting to localhost [127.0.0.1] port 22. debug1: Connection established. debug1: identity file /c/Users/MoreFreeze/.ssh/identity type -1 debug3: Not a RSA1 key file /c/Users/MoreFreeze/.ssh/id_rsa. debug2: key_type_from_name: unknown key type '-----BEGIN' debug3: key_read: missing keytype debug3: key_read: missing whitespace // above it repeats 24 times debug2: key_type_from_name: unknown key type '-----END' debug3: key_read: missing keytype debug1: identity file /c/Users/MoreFreeze/.ssh/id_rsa type 1 debug1: identity file /c/Users/MoreFreeze/.ssh/id_dsa type -1 ssh_exchange_identification: Connection closed by remote host it seems my private keys has wrong format? And I find that there are exactly 25 line in private keys without "BEGIN" and "END". I'm confused why it said NOT RSA1 key, I totally ensure it is RSA 2 key. Any advises are welcome. btw, I have read first 3 pages on google about this problem.

• Messaging pattern question

  - by Al Bundy

  Process A is calculating values for objects a1, a2, a3 etc. and is sending results to the middleware queue (RabbitMQ). Consumers read the queue and process these results further. Periodically process A has to send a snapshot of these values, so consumers could do some other calculations. Values for these objects might change independently. The queue might look like this a1, a1, a2, a1, a2, a2, a3... Consumers process each item in the queue. The snapshot has to contain all objects and consumers will process this message for all objects in one go. So the requirement is to have a queue like this: a1, a1, a3, a2, a2, [snapshot, a1, a2, a3], a3, a1 ... The problem is that these items are of different types: one type for objects like a1, a2 and other for a snapshot. This means that they should be processed in a diferent queues, but in that case there is a race condition: consumers might process objects before processing a snapshot. Is there any pattern to solve this (quite common) problem? We are using RabbitMQ for message queueing.
